TOOL.

Patented Oct. 26, 1909.

Application filed May 25, 1908, Serial No. 434,730. Renewed March 3,1909. Serial No. 481,089..

T 0 all whom it may concern:

Be it known that I, J ACOB SPAAR, a citizen of the United States, andresiding at Katonah, in the county of Westchester and State of New York,have invented certain new and useful Improvements in Tools, of which thefollowing is a specification, such as will enable those skilled in theart to which it appertains to make and use the same.

This invention relates to tools for use in securing the lenses ofeye-glasses or spectacles to the nose-bridge member of the saideye-glasses or spectacles, and for securing temple pieces to said lenseswhen spectacles are employed, and the object thereof is to provide animproved tool of this class which is used in connection with fasteningdevices as shown and described in a companion ap plication executed andfiled by me of equal date herewith, and in which the tool which formsthe subject matter of this application is also shown and described.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawing forms a part, in which the separate partsof my improvement are designated by suitable reference characters ineach of the views, and in which Figure l is a side view of my improvedtool with part of the construction in section, and showing also aneye-glass or spectacle lens together with one of the clips or studs usedin connecting the lens with the nosebridge member of a pair ofeye-glasses or spectacles, and showing the method of operating the toolin securing the clip or stud to the lens or the lens to said clip orstud, Fig. 2 an end view of the tool looking in the direction of thearrow m of Fig. 1, and Fig. 3 a view of the lens and clip or stud shownin Fig. 1 after the operation of securing the lens to said clip or studis completed.

In the practice of my invention, I provide a tool a of the same generalform as a J pair of pliers, said tool being composed of parallel jaws aand a pivotally connected at a and provided with extended shanks aforming handles the compression of which will force the jaws a and (1together.

Passing through one of the jaws of the tool, the jaw a as shown in thedrawing, is a rotary pin 72 provided at its inner end with a head 6 theinner end portion of which is wedge-shaped in form, and the outer end ofthe pin 7) is provided with a large milled head 6 between which and thejaw a is placed a friction spring or similar device I). The other jaw aof the tool is provided with an outwardly directed elongated boss 0,andpassing inwardly through said boss and said jaw is a pin or shaft 65provided at its outer end with a large milled head d which forms ahandle, and the inner end of the pin d is preferably made wedge-shapedin form as shown at CF, and provided centrally with a projecting beveledpoint 6%, and mounted on the inner end portion of the pin 0! adjacent tothe jaw a .is a washer e which is held in place by a key pin 6 passedthrough the pin or shaft d. I have also shown at f a clip or studemployed in connection with the nose-bridge member of a pair ofspectacles or eye-glasses for connecting a lens 9 therewith, and saidclip or stud is provided with parallel jaws f and in the operation ofconnecting the lens with the clip or stud I provide a screw it providedat one end with the usual head 71?, and the other end of which isprovided with a longitudinal socket or bore i11 and I also preferablyprovide a washer 2' through which the end of the screw it passes, andsaid washer is provided with an aperture, the walls of which are beveledoutwardly as shown at 2' The length of the screw it is greater than thecombined thickness of the jaws f of the clip or stud f, the lens 9 andthe washer 2' and the end portion of said screw in which the socket orrecess h is formed is not threaded.

In the operation of securing the lens 9 in the clip or stud j, the screwit is passed through the jaws f of said clip or stud and through thelens and through the washer 2', and the tool a is manipulated so as toplace the head 12 of the pin 5 on the head it of the screw it, and thepoint d of the pin or shaft d in the socket or recess h of the screw it.The handle members a of the tool are then firmly compressed by one handthus forcing the jaws a and a together, and at the same time the pin orshaft d is turned by the other hand, and the end of the screw h in whichthe socket or recess 71 is formed is expanded as shown in Fig. 3 and thelens g is securely locked and held in the clip or stud f and will notwork loose under any circumstances.

The clip' or stud f, the screw it and the washer 2' form no part of theinvention described and claimed herein, but constitute the subjectmatter of a companion application hereinbefore referred to.

The object of the spring 6 is to hold the pin 6 against rotation When itis not desired that said pin should rotate, and the head Z2 of the pin 6constitutes a handle by which said pin may be rotated when necessary,and the object of making this pin rotary is to provide means whereby thewedge-shaped inner end or head 6 thereof may becaused to engage the headof the screw h in any position in which said screw may be.

One of the shank 0r handle members a of the tool is provided adjacent tothe pivotal connection of said shank or handle memberswi-th an inwardlydirected stud which is adapted to strike on the other shank or handlemember, and thus limit the extent to which the jaws a and a can bebrought together, the object of this construction being to prevent theforcing of the inner ends of the pins 6 and pin or shaft d together andthus injuring said ends.

Having fully described my invention,

secure by 2. A tool of the class described provided with parallel jaws,a rotary pin mounted'in one of said jaws, and a rotary shaft mounted inthe other, said pin and said shaft being 7 provided at their outer endswith heads forming handles, and a friction spring placed between thehead of the pin and the jaw through which said pin passes;

In testimony that I claim the foregoing as my invention I have signed myname in presence of the subscribing witnesses this 22nd day of May,1908.

JACOB SPAAR.
